caption Attribute (submit Element)
Defines the name of the submit button and corresponding menu item that will appear on the File menu when a user is filling out a form.
The caption attribute is an optional attribute of the submit element.
The default value is "Submit", but any text string can be used. If the caption attribute is missing or is set to an empty string, the default value is used. The "&" characters can be used to create a keyboard shortcut for the submit menu item.
